Monitor won't turn on after "sleep"

Hi,
I have an Apple Studio Display 17" hooked up to a New Mac Pro, running 10.4 Tiger. When the computer goes to sleep the monitor won't come back on when I wake it unless I shut the monitor off and turn it back on again. Why?

What did ssh probing tell you.
Try using PC blindly. For example, leave music player on screen, wait for the fault to appear and than start it. If you hear the sound, then it is either:
Your closed-source driver mistake. Try changing it's version either side or replacing with open-source one. For radeon it is really better already.
Your monitor can't wake up from sleep. Nothing can help it, then. When rebooting PC, it gets a special signal, different from that on sleep.

  • Turn on! My mac won't turn on after sleeping!

    Ever had a problem where your computer won't turn on after sleeping for a few minutes? (I've discovered that too many downloads cause this) Anyway... have you ever tried pushing the power button for one second? Try it! It's been working for me! Hope this helped!

  • Monitor won't wake up after sleep mode

    Does anyone know how to fix the monitor, so it starts up after sleep mode? When my computer comes out of sleep mode the monitor doesn't always come on. Does anyone else have this problem and do you know the cause? The computer is only a few months old and hadn't had any problems.
    Thanks,
    Shaneil

    Well my solution may not be the most cientific one but it works for me (at least until the real solution comes to the public)...
    My computer has the problem that when it goes to sleep mode she never comes back... but it the screen that does not comes back... all the system is workin in behind (its like the brightness level was set on the less power possible) so i had to turn off the computer and had to do for a long time some times i had to wait that the computer cooled off a little and then try again to turn it on... I some tried things that the support page of apple said it could be... but did worked out... i dont know i think is a problem over 2 factors...
    1. heating (the screen generates to many heat but, TO MANY!)
    2. tiger os the OS "sleep mode" (it knows that the screen its heating a lot and tries to go to sleep to prevent over heating and damage)
    So based on this i tried conecting a external monitor to the computer while she was unable to "awake" (or to show some thing in the screen)... and it worked whit no problem at all... so my conclusion was to prevent the over heating (1st factor) and the sleep mode (2nd factor)... so I deactivated the sleep mode setting up the computer to a never sleep mode... and to prevente the over heating well I use a low bright and when i need more brightness (to se the colors of what im doing or some thing like that) I use high brightness... when I away I set the brightness level to no brightness so there is no over heat and no sleep mode (cus if it is deactivated and it over heats it will go to sleep anyway...
    Soooooo....
    1. deactivate Sleep mode...
    2. Activate a Screen saver...
    3. And remember to contro your brightness your self... and turn it off when you are not using your computer...
    well i hope it works for some body :P cya...

  • Airport won't turn on after sleep

    Recently purchased 2 new imacs(1-24", 1-20"). They are both having the same problem. When I wake them up from a powersave sleep the airport is turned off. This wouldn't be a problem except it wont turn back on. If I click to turn it on it doesn't do anything at all. If I go to assist me -> diagnostics it just says scanning... but never does anything else. The only way I can get back up and running is a restart. This is a problem because I run software that needs to send a backup to the server on shutdown. I have temporarily set the powersave up to 3 hours, but I would much rather fix the problem than work around it.

    Hi, When the computer goes into sleep mode, it is like shutting it down, in that it halts any and all processes.
    Because nothing is happening until it wakes back up, that is why Entourage won't get it's mail. MSN will disconnect whenever the computer is put to sleep (or more annoyingly, whenever it damned feels like it).
    So yes, this is normal behaviour with sleep mode, and the only workaround I know of is to not have the computer sleep. (But the monitor can always turn off, and the hard drives spin down.)

  • Screen won't turn on after sleep for newest macbook pro (Feb 26 2011)

    Hi!
    I just bought the 13' Macbook Pro with an 2.7GHz dual-core i7 processor and 500GB of space, the $1500 model. I am having a problem with the screen and I am wondering if I should be worried about it or if anyone else has noticed it. If it continues, I will have to take it into the store and see if I can get it fixed.
    My macbooks screen will not turn on after it falls asleep for a long period of time. The first night I had this computer, it was playing music and I turned the screen brightness all the way down/off and then I fell asleep. The energy settings were set so that the computer would fall asleep after 20 minutes. Pathfinder, F.lux and iTunes were the only application running at the time. When I woke up the next morning, the light on the computer's side indicating it was asleep was slowly fading in and out (as expected). I hit some keys on the keyboard and the keyboards backlighting turned on after a few seconds.
    But the screen did not turn on. I tried adjusting the screen brightness on the keyboard and nothing happened. After a few minutes, I held down the power button and heard the computer turn off. I turned the computer back on, AND THE SCREEN LOOKED VERY STRANGE. I could see part of iTunes fragmented/segmented into 5 or 6 sections across the screen. There were also strange lines going across the screen. It looked kind of like a leftover image of iTunes that could be solved with a screen refresh. I turned off my computer again and turned it back on about two more times, and then the screen would simple just not turn on.
    As I was packing up to go to the Apple Store, I tried one more time to turn my computer on and the screen was working fine. This was yesterday, and for the rest of the day the computer seemed to work fine. However, I don't think I let my computer fall asleep all day yesterday because I was using it so much.
    Basically the same thing happened this morning when I woke up, except to a lesser degree. My computers screen was unresponsive after keyboard input, but I was able to get music to play from my speakers. I restarted it and it seems to be working fine. I didn't see the screen do that weird fragmentation thing this time.
    I think something about the sleep function is interfering with my computer's screen. Or perhaps Pathfinder or F.lux have something to do with it. F.lux, by the way, is a application that turns the screen a dark yellowish at night to help your eyes. But I have friends that use this application and I myself have used it for a while and we have never had this problem. Then again, none of them have a 13 inch with an i7.
    Does anyone know about this problem and have advice that would save me a trip to the Apple store?
    thanks!

    Bad news and good news. The bad news is that it happened again this morning. The good news is that I finally found something interesting in the console log, at the exact second my clock is stuck when the machine is failing to wake from sleep:

    From when the problem apparently starts (some point in the night while my machine is idle and supposedly asleep) until when I discover it and reboot the machine, I get dozens or hundreds of the above messages. Now somebody just needs to figure out what that means and stop it from happening...

  • Newest Macbook won't turn on after sleep mode

    I have the 17" Macbook Pro I guess the base model (?), bought in september of 2012. I turned it on today perfectly fine for about a half an hour. I closed the screen just like I would any other time normally but just now when I opened it back up it won't turn back on. I tried the power button several times but nothing, the power is fine since it's plugged in with the green light on. I don't understand what is going on... help!

    I am investigating these reports, and will provide updates as this investigation develops.

    After tablet goes to sleep due to no use it wont turn on back when pressin power button. Agterv some time (could be hours) and multiply presses on power button it turns on for some reason. Can't really figure out any preconditions ore sequences. But it happens almost every time it stays in sleeep mode for a long time, which is extremely annoying as tablet can't be use same moment when it is needed.

  • Rmbp 13" 2014 won't turn on after sleep battery drain

    Hi peeps,
    Today, my rmbp 13" from 2014 failed to start after it's battery ran dry while it was sleeping.
    I have let it charge for a while (about 15 minutes) and then it wanted to turn on again.
    My question is: is this normal behavior? I found another thread with kind of the same question but it was irrelative due to other issues being present in that particular thread.
    Best regards,
    IT07.

  • Screen won't turn on after sleep

    Hey guys, I've only had my GT-72 for a month and recently I've been having issues when putting mine to sleep.
    I'll close the lid, come back later, open the lid and the power/gpu lights/front lights turn on, but that's it. I also hear the hard drive fire up too. The screen although does not turn on and no matter if I tap the keyboard/peripheral mouse, or power button it is unresponsive. The only way I can get the laptop back is to do a hard shutdown by holding the power button and restarting it.
    Any solutions or ideas what may be causing this?
    Thanks all!

    The possible causes of the situation could be a lot. You had better contact service center for precise testing . If you insist to try bios renewing ,you can refer to the following link of msi website.>>http://www.msi.com/files/pdf/Flash_BIOS_by_UEFI_BIOS_Setup_Utility_en.pdf

  • Laptop screen won't turn on after sleep, requires reboot

    I close the screen to my Macbook Pro when going to be away for a length of time.  Until recently, the screen would turn on when I opened the computer.  Now, although the computer is on, the screen won't light up when I open it.  The laptop now requires a forced rebook in order for the screen to work.  Will this require a service call?

  • 8560w Wireless Radio won't turn on after sleep mode

    Anyone know the fix for the 8560w not turning on it's WiFi radio post sleep mode.  It doesn't happen everytime, but most of the time.  I will be at my workstation and when I close the lid, go to my meeting and turn it back on the wireless is off and I have to go to the "Windows Mobility Center" to turn it back on.
    Any ideas or thoughts would be greatly appreciated.

    can anyone help, my late 2010 MBA's - OS X Lion 10.7.5 wifi won't turn on after a deep sleep.. thanks..!

    Hi John,
    Thanks for the additional information.  What I would try next is resetting System Management Controller:
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

    If not then your sleep button is broken, you will need to get it serviced.

    P.S. I just noticed; when I hold the power and home button at the same time while it's plugged in as if I was going to restart it, my computer acts as if I'd plugged it in again (it makes the USB notification sound, itunes opens up again, I get the same "your iphone is in recovery mode" message, etc.), but that's the only response I've been able to get from pressing anything on the iphone. thanks again.
